2. Sensor Synchronization
After installing batteries in both units, the main display unit should automatically attempt to connect with the outdoor sensor. This may take a few minutes. Ensure both units are within range (up to 100 ft.) and not obstructed by large metal objects or thick walls.
If the outdoor temperature does not appear after a few minutes, press and hold the "CH" button on the main unit to initiate a manual search for the sensor.
3. Col·locació
Unitat de visualització principal: Place the main unit indoors on a flat surface, such as a tabletop or desk. Avoid direct sunlight or proximity to heat sources (e.g., radiators, appliances) as this can affect indoor temperature and humidity readings.

Figura 5: The main display unit positioned on an indoor surface, demonstrating its tabletop mounting capability.
Sensor exterior sense fil: Position the outdoor sensor in a shaded, dry location outdoors, protected from direct rain and sunlight. Direct sunlight will cause inaccurate temperature readings. A north-facing wall or under an eave is often ideal. The sensor can be mounted using a screw through the hanging hole on its back.
